LM4040 PRECISION MICROPOWER SHUNT VOLTAGE REFERENCES Description Pin Assignments The LM4040 is a family of bandgap circuits designed to achieve (Top View) precision micro-power voltage references of 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V. The devices are available in 0.2% B-grade, 0.5% C-grade, and 1% D-grade initial tolerances. They are available in small outline SOT23 surface mount packages, which are ideal for applications where space is at a premium. Excellent performance is maintained over the 60A to 15mA operating current range with a typical temperature coefficient of only 20ppm/C. The device is designed to be highly tolerant of capacitive * Pin 3 must be left floating or connected to pin 2 loads, which maintains excellent stability. SOT23 This device offers a pin for pin compatible alternative to the LM4040 voltage reference.

These are stress ratings only functional operation of the device at conditions between maximum recommended operating conditions and absolute maximum ratings is not implied. Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time. (Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling and transporting these devices.)
